Abstract: An exemplary method and associated architecture for reducing NOx and particulate matter emissions in an exhaust stream may include passing the exhaust stream through a catalytic oxidation reactor; passing the exhaust stream through a two-way selective reduction catalyst particulate filter located downstream of the catalytic oxidation reactor, wherein the two-way selective reduction catalyst particulate filter may include a wall flow filter substrate having internal walls coated with a first selective catalytic reduction catalyst; and passing the exhaust stream through a catalytic reduction reactor located downstream of the two-way selective reduction catalyst particulate filter, wherein the catalytic reduction reactor may include a second selective catalytic reduction catalyst.

Abstract: Automated sample processing systems may include onboard efficient high-speed mixing of at least two components with an automatic vertical force fluidic turbulent component mixer of which a mixed component may be aspirated and high-speed dispensed in a mixing vial. Other aspects may include single sweep applying a multi-treatment cleaning cycle to at least one slide. A multi-treatment cleaning cycle may include a washing treatment and a drying treatment. In yet other aspects the present invention may include an automated recovery sample processing system with the capability of detecting at least one immediate condition of a fortuitously terminated automatic sample processing run and perhaps even an automatic terminated sample processing run reconstruction calculator.

Abstract: A delivery apparatus for selectively delivering one or more liquid reagents into a reaction or test chamber (2), especially of an assay apparatus, the apparatus comprising: one or more respective storage chambers (5,6) for containing the one or more liquid reagents and arranged generally above the reaction or test chamber (2); and a plunger element (4) arranged and operable for insertion into the mouth of a selected storage chamber so as to displace a selected reagent from therewithin into the reaction or test chamber (2) generally therebelow by gravitational liquid overflow from the mouth of the chamber. The apparatus may conveniently be provided as a discrete delivery unit, with the storage chambers (5,6) prefilled with the selected reagents.
Abstract: An osteochondral centrifugation system for providing an osteochondral centrifuged core from a graft such as femoral condyle, for example. The centrifugation system may be used either in the operating room or, alternatively, at a tissue banking facility at the time of processing. The osteochondral centrifuged core is formed by (i) removing an osteochondral core from a graft; (ii) placing the osteochondral core in a centrifugation system to remove blood, lipids, or other potentially antigenic or contaminating materials, and to obtain a centrifuged core; and (iii) optionally, subjecting the centrifuged core to a material that reduces the chance of disease transmission and aids in the healing of the recipient site to which the centrifuged core is to be transferred.
Abstract: The microfluidic system is constituted of modules that comprise one microfluidic unit and one corresponding electric control unit each and that are retained on a rear panel unit next to each other in a row. To prevent the formation of accumulation of ignitable or toxic gas mixtures a fluid conduit for a rinsing fluid extends through the rear panel unit. Branches lead from said fluid conduit to the modules, and said branches flowing into respective distributor compartments that extend vertically across the module height in the modules. Said distributor compartments are delimited in relation to the interior of the respective module by a distributor panel that is provide with openings. The interior of the respective module comprises, on its lower or rear surface, an exit opening for the rinsing fluid.
